This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Old reinforced concrete buildings are vulnerable to seismic actions as they were built in accordance with non-seismic code provisions and suffer from poor material quality and/or reinforcement detailing. Moreover, many buildings were constructed without even basic design code recommendations. Consequently, their structural components, in particular beam-column joints, suffer from a wide range of deficiencies. These joints may deteriorate severely under seismic actions leading to extensive damage and collapse. The current study aims to develop an understanding of the behaviour of exterior beam-column joints with shear strength and anchorage deficiencies, and to examine a strengthening solution using post-tensioned metal strips in upgrading their performance. A multiphase experimental programme was conducted including small and medium-scale beams with inadequate lap splices loaded in tension and deficient isolated full-scale exterior beam-column joints subjected to quasi-static cyclic loading. In the beam tests, deficient splices were investigated under different confinement conditions, namely, unconfined, internally confined by steel stirrups, and externally confined by metal strips. Test parameters included concrete cover, confinement ratios, concrete quality, and bar diameter. Providing post-tensioned external confinement had a considerable impact on the behaviour, and resulted in sizable enhancements in strength and ductility. Parametric studies were conducted to identify the parameters most influencing the contribution of external confinement to bond. A bond stress-slip model is proposed that can be used to predict and simulate the behaviour of splices strengthened by post-tensioned metal strips. This model was implemented in FE models of beams and showed good correlation with the measured response. In the joint tests, four full scale exterior RC beam-column joints were tested under cyclic loading. The joints experienced severe cracking and damage including a shear mechanism in the panel zone. The joints failed prematurely at about 50% of their nominal flexural strength. Strengthening the joints with post-tensioned metal strips led to an improved performance, higher energy dissipation and more controlled shear failure along with moderate damage in the beam. An enhanced ACI-based strut-and-tie joint model is proposed and verified against the current test results and results by others. The model can be used for strengthened specimens as well as unconfined exterior joints and it accounts for different beam anchorage lengths. A quad-linear shear stress-strain model is proposed to simulate the behaviour of strengthened joints. The model was implemented in a finite element panel-zone scissors model. The scissors model was incorporated in nonlinear static and cyclic analyses. The simulated response was found to represent the joint behaviour reasonably well. A full-scale two storey reinforced concrete framed building was designed and tested on a shaking table, in cooperation with different researchers and academic partners. The building was substandard with a multiple range of deficiencies in the joint regions and connecting elements. The bare building suffered severe damage under small seismic intensities. Upgrading the structure with schemes of post-tensioned metal strips led to a considerably enhanced performance.

Book Synopsis Displacement-based Seismic Design of Reinforced Concrete Buildings by : fib Fédération internationale du béton
Download or read book Displacement-based Seismic Design of Reinforced Concrete Buildings written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2003 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief summary of the history of seismic design as given in chapter 1, indicates that initially design was purely based on strength or force considerations. When the importance of displacement, however, became better appreciated, it was attempted to modify the existing force-based approach in order to include considerations of displacement, rather than to totally reconsider the procedure on a more rational basis. In the last decade, then, several researchers started pointing out this inconsistency, proposing displacement-based approaches for earthquake engineering evaluation and design, with the aim of providing improved reliability in the engineering process by more directly relating computed response and expected structural performance. The main objective of this report is to summarize, critically review and compare the displacement - based approaches proposed in the literature, thus favouring code implementation and practical use of rational and reliable methods. Chapter 2 Seismic performance and design objectives of this report introduces concepts of performance levels, seismic hazard representation, and the coupling of performance and hazard to define performance objectives. In fact, for displacement analysis to be relevant in the context of performance-based design, the structural engineer must select appropriate performance levels and seismic loadings. A critical review of some engineering limit states appropriate to the different performance levels is therefore proposed. In chapter 3 Conceptual basis for displacement-based earthquake resistant design, the fundamental principles associated with displacement of the ground during an earthquake and the effects, in terms of displacement, in the structure, are reviewed. The historical development guides the presentation with a review of general linear and nonlinear structural dynamics principles, general approaches to estimate displacement, for both ground and structure, and finally a general presentation of the means to measure and judge the appropriateness of the displacements of the structure in section. Chapter 4 Approaches and procedures for displacement-based design can be somehow considered the fundamental part of the report, since a critical summary of the displacement - based approaches proposed by different researchers is presented there. Displacement - based design may require specific characterization of the input ground motion, a topic addressed in Chapter 5 Seismic input. In general, various pertinent definitions of input motion for non-code format analysis are included, while peak ground parameters necessary for code base shear equations are only addressed as needed for the definition of motion for analysis. Chapter 6 Displacement capacity of members and systems addresses the fundamental problem of evaluating the inelastic displacement capacity of reinforced concrete members and realistic values of their effective cracked stiffness at yielding, including effects of shear and inclined cracking, anchorage slip, bar buckling and of load cycling. In Chapter 7 Application and evaluation of displacement-based approaches, some of the many different displacement based design procedures briefly introduced in Chapter 4 are applied to various case studies, identifying and discussing the difficulties a designer may encounter when trying to use displacement based design. Results for five different case studies designed in accordance with eight different displacement based design methods are presented. Although in general case studies are considered a useful but marginal part of a state of the art document, in this case it has to be noted that chapter 7 is possibly the most innovative and fundamental part of the whole report. The conclusions of chapter 7 are the fundamental and essential conclusions of the document and allow foreseeing a bright future for displacement - based design approaches. The state-of-art report has been elaborated over a period of 4 years by Task Group 7.2 Displacement-based design and assessment of fib Commission 7Seismic design, a truly international team of experts, representing the expertise and experience of all the important seismic regions of the world. In October 2002 the final draft of the Bulletin was presented to the public during the 1st fibCongress in Osaka. It was also there that it was approved by fib Commission 7Seismic Design.
Book Synopsis Nonlinear Analysis of Reinforced Concrete Frames Subjected to Abnormal Loads by : Ignac Joseph Emil Zajac

This book was released on 2007 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to analyze reinforced concrete frames subjected to abnormal loads. Structures are rarely subjected to abnormal loads, however, when they are subjected to them, it can lead to a progressive collapse. The World Trade Centers in New York City and the Alfred P. Murrah building in Oklahoma City are examples of structures being deliberately subjected to abnormal loads. Structures can also experience unintentional abnormal loading. Examples include the Ronan Point apartment building in Canning Town, England and Husky Stadium at the University of Washington. Consequently, many analysis and design standards now explicitly account for abnormal loads and try to mitigate their effects. This study presents the development of a nonlinear computer analysis program for reinforced concrete frames. The method of analysis involves discretizing a two dimensional reinforced concrete frame into a series of beam-column elements. The element is linear-elastic, however, its end-sections model nonlinear behaviour of a total member by a series of springs. The springs represent the post-elastic stiffness of the end-sections. The post-elastic stiffness of a member-section is obtained from a post-elastic force-deformation response, which is first obtained by performing sectional analysis on a reinforced concrete section using a public domain computer program. The post-elastic force-deformation responses are modeled as either bilinear or trilinear. So-called stiffness degradation factors, which are defined as the ratio of elastic to elastic plus post-elastic deformation of a member-section, are used in modifying the elastic stiffness coefficients in the element stiffness matrix to account for the nonlinear behaviour. Once a reinforced concrete frame enters the post-elastic range of response the analysis procedure becomes incremental. The stiffness degradation factors are calculated at each load increment and the degree of post-elastic stiffness degradation is progressively tracked throughout the load history. The program also has the capability of performing a progressive collapse analysis whereby debris loads caused by falling members are calculated and applied to the structure. A series of example problems are presented to demonstrate the computer analysis program.
